Improvement in water-wheel cases



UNITED STATES YWILLIAM H. SNYDER, OF PHELPS, NEW YORK;

IMPROVEMENT IN WATER-WHEEL CASES.

Specification forming part of Letters Patent No. 119,1947 datedSeptember 19, 1871.

by declare that the following is a full, clear, and

exact description thereof, which will enable others skilled in the artto make and use the same, reference being had to the accompanyingdrawing forming part of this specification, in which- Figure 1 isavertical central section of my improved water-wheel casetaken throughthe line a' Fig. 2. Fig. 2 is a horizontal section of the same takenthrough the line y y, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention has forgits object to improve the construction of thecylinder-gate of water-wheel cases so as to confine the water until itreaches the wheel, to make its action upon the wheel more direct andeffective; and it consists in the water-stops in combination with thecylindrical gate and sluice-Ways or chutes of the case of the' wheel, ashereinafter more fully described.

A is the case of the wheel, in which the shutes or sluice-ways B areformed, and within which the wheel revolves. which shuts down around theoase A to close the chutes B, wholly or to any desired extent. To theinner side of the cylindrical gate C are attached stops D, which aremade of such a size and shape as to fit accurately into the chutes B andform a top wall to said chutes, said stops extending into the wheel. Bythis means the water is coniined and kept from spreading while passingthrough the chutes, causing it to produce its full effect upon thewheel.

Having thus described my invention7 I claim as new, and desire to secureby Letters Patent- A Water-wheel embracing the exterior casing, providedat its lower part with a series of angular flanges, D, independentlyconnected and removable at will, and the interior casing provided withthe chutes B, between which the iianges are arranged to control the flowof the Water to the wheel, substantially as set forth.
